Angelina Jolie has revealed she wears urine-soaked dresses on the red carpet if one of her children has an accident and she doesn't have time to change

The 'Changeling' star - who raises six children with partner Brad Pitt - admits juggling her family and career sometimes causes problems, particularly when preparing for a big event with limited time.

She said: "The only time fame and family life ever collides is if, you know, we're trying to get ready for some event where we have to walk a carpet and somebody gets peed on, and figures, 'Oh well, I guess we'll be wearing that this evening.' "

The actress - who was previously married to Jonny Lee Miller and Billy Bob Thornton - also admitted she isn't sure why she and Brad have never tied the knot, but she is happy with their relationship.

Speaking on British TV show 'GMTV' today (18.11.08), she added: "I don't know - it's not that I'm hesitant. We jumped into being a family first, and that just seems like the biggest commitment you could possibly make anyway. So, it doesn't feel like anything is lacking."
